HINGE Filed April 4, 1940 Inventor A iiorney Patented July 23, 1940 UNITED STATES HINGE Alfred Lachwitz, Flushing, N. Y.

Application April 4, 1940, Serial No. 327,895

3 Claims.

The present invention relates to new and useful improvements in hinges particularly for doors and has for its primary object to provide, in a manner as hereinafter set forth, a hinge comprising a novel construction and arrangement whereby the door may be expeditiously adjusted vertically as desired.

Another very important object of the invention is to provide a hinge of the aforementioned character wherein the adjusting means will be substantially invisible.

Other objects of the invention are to provide a hinge of the character described which will be comparatively simple in construction, strong,

durable, highly efficient and reliable in use and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in vertical section through 5 an adjustable hinge constructed in accordance with the present invention, showing said hinge ,in open position.

Figure 2 is a rear perspective view of the hinge.

30 Figure 3 is a view in horizontal section, taken substantially on the line 3-3 of Figure 1.

Figure 4 is a detail View in perspective of the pintle.

Referring now to the drawing in detail, it

35 will be seen that the embodiment of the invention which has been illustrated comprises a pair of leaves I and 2 of suitable metal. The leaves I and 2 are provided with tapered openings 3 for the reception of screws 4 for securing said leaves to the frame 5 and the door 6. It will be observed that the leaf I is secured to the frame 5 and that the leaf 2 is secured to the door 6.

The leaf I has formed on one edge thereof integral, vertically spaced internally threaded 45 eyes 1. Formed on one of the vertical edges of the leaf 2 is a comparatively long eye 8 which is positioned between the eyes 7 with its ends spaced therefrom. It will be observed that the eye 8 is of smaller diameter than the eyes I.

50 Threadedly mounted in the eyes 'I' are adjusting screws 9 which are engaged with the upper and lower ends of the eye 8 for raising and lowering the leaf 2 with the door 6 thereon. The eye 8 is journaled on a pintle I0 the end portions 55 of which are engaged in sockets II which are provided therefor in the adjusting screws 9. The outer ends of the adjusting screws 9 are provided with heads I2 for receiving a suitable tool for turning said adjusting screws.

Set screws I3 are provided in the eyes 1 for 5 securing the screws 9 in adjusted position. Caps I4 are threaded on the exposed end portions of the adjusting screws 9. The reference numeral I5 designates a split metallic sleeve which encloses the eye 8. The sleeve I5 extends between 0 the eyes i and is flush with the outer peripheries thereof. It may be well to here state that the eye 8 is slidable in the sleeve I5 and that said sleeve turns with the leaf 2.

It is thought that the operation of the hinge 15 will be readily apparent from a consideration of the foregoing. Briefly, when the door 6 is opened or closed the eye 8 turns or rotates on the pintle ID, the sleeve I5, as hereinbefore stated, turning with said eye 8. The sleeve I5, extending between 20 the eyes I, conceals the projecting inner end portions of the adjusting screws 9 and closes the spaces between the ends of the eye 8 and the eyes 'I. To adjust the door 6 vertically, the set screws I3 are loosened and the caps I5 are removed thereby exposing the headed ends I2 of the adjusting screws 9. Then, the adjusting screws 9 are threaded upwardly or downwardly in the eyes I for raising or lowering the leaf 2 with the door 6 thereon. When the desired adjustment has been made the caps I4 are replaced and the set screws I3 tightened.

It is believed that the many advantages of an adjustable hinge constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

1. A hinge comprisinga pair of leaves, spaced eyes on one of said leaves, screws threadedly mounted in said eyes and having sockets therein, a pintle having its end portions sli daloly mounted in the sockets, and a comparatively long eye on the other leaf journaled on the pintle and engaged with the screws for adjustment thereby.

2. A hinge comprising a pair of leaves, spaced eyes on one of said leaves, screws threadedly mounted for adjustment in said eyes and having sockets therein, a pintle having its end portions slidably mounted in the sockets, an eye on the other leaf journaled on said pintle and engageable at its ends by the screws for adjustment thereby, set screws threadedly mounted in the first named eyes and engaged with the adjusting screws for securing said adjusting screws in position, and caps threadedly mounted on the adjusting screws. p

3. A hinge comprising a pair of leaves, spaced internally threaded eyes on one of the leaves, screws threadedly mounted in the eyes and having sockets therein, a pintle having its end portions slidablymounted in the sockets, an elonof the screws, the second named eye being slidable in the sleeve, said sleeve rotating with said second named eye.
